low lymphocytes / petechiae / rash

Recently I noticed a red rash on my arm. Slightly raised. It did not itch. At the same time I had petchiae appear all over my body.

I had the petechiae appear two times before, maybe a year apart.

I know that the petechiae appeared in January 2005 (almost 2 years ago).

They were more extensive this time. I think in all cases they appeared within a few days of air travel if that's relevant. Also, I just got over a bad cold that lasted about 3 weeks.

The petechiea and rash are almost gone after 3 days...

I had blood tests done this time while the petchiae and rash were still present. The physician said the tests looked normal and that I probably had an allergic reaction to something. He gave me prednisone.

My CBC was off a little but the Absolute Count was in normal range so my Doctor didn't repeat it (but then again I am changing doctors because she can't give me an accurate anything! She will agree with the Doctor that says it's a lymph node and then agree with the doctor that says it's not - long story!) I have a lump in the back of my neck and two swollen nodes under my arm. Pressure in my head that does not go away with constant ringing in my ear - Two Cat Scans an MRI and MRA are all negative - Two ER Docotors Confirmed Lymph node in neck - Neorologist said Lymph node - My doctor agreed - ENT Specialists says knotted muscle - Mammogram negative for cancer - My Neutrophils High and Lymphs Low, also negative for HIV. I have a doctors appointment with another doctor tomorrow and hopefully I will get answers! I also have what I thought was Petechaie (spelling?) but the tiny red dots are not raised and it is not an allergic reaction, I was told it was basically part of the aging process (I am 40)

I sometimes think that I have RA - and I wonder at times if I could have Lyme Disease.

My last blood results in March also said that I have low lymphocytes and lymphs. What does this indicate? Anything to worry about? Even my results have an "L" by them for low.
Thanks!
Lymphocytes%--22.6L range 24-48
